A suspect fired his gun into the air Monday morning after trying to rob a man in San Francisco’s Duboce Triangle neighborhood as the man walked to work.

The September 26 incident started at about 9 a.m in the 200 block of Noe Street, near 15th Street. The suspect approached the victim and tried to take his briefcase, police said.

When the victim, 61, refused to let go of the case, the suspect produced a handgun and fired a shot into the air. The suspect, whom police described only as a black male in his 20s, then fled in a vehicle.
